Existing LiDAR-to-image cross-view localization methods struggle in large-scale scenarios due to limited semantic alignment and the modality gap between point clouds and satellite images. This paper introduces the large-scale LiDAR-to-image geo-localization pipeline called GeoISF. GeoISF introduces an instance semantic forest constructed using WordNet, which enhances temporal semantic representation and discriminative power by integrating semantic trees from multiple frames. By leveraging environmental semantic representation as a shared medium, GeoISF effectively bridges the modality gap and improves semantic matching accuracy. Extensive experiments demonstrate the superior performance of GeoISF in large-scale cross-view localization, 13.22 times better than the parallel LiDAR-to-image method in the R@10 metric on the KITTI dataset. The proposed method addresses the existing gap in large-scale LiDAR-to-image cross-view localization, offering a robust solution to the computational and accuracy challenges inherent in such scenarios. We will release the code as an open-source resource available online for the broader research community.", "url": "https://wpnews.pro/news/geoisf-instance-semantic-forest-inspired-large-scale-cross-view-geo-localization", "canonical_source": "https://arxiv.org/abs/2606.28371", "published_at": "2026-06-30 04:00:00+00:00", "updated_at": "2026-06-30 04:24:09.824204+00:00", "lang": "en", "topics": ["computer-vision", "autonomous-vehicles", "ai-research"], "entities": ["GeoISF", "WordNet", "KITTI dataset"], "alternates": {"html": "https://wpnews.pro/news/geoisf-instance-semantic-forest-inspired-large-scale-cross-view-geo-localization", "markdown": "https://wpnews.pro/news/geoisf-instance-semantic-forest-inspired-large-scale-cross-view-geo-localization.md", "text": "https://wpnews.pro/news/geoisf-instance-semantic-forest-inspired-large-scale-cross-view-geo-localization.txt", "jsonld": "https://wpnews.pro/news/geoisf-instance-semantic-forest-inspired-large-scale-cross-view-geo-localization.jsonld"}}
